Hello Chaitanya,

There are very few mobile phones on the market today with the functionality to act as a GSM modem. (Very) old dumb phones often have that capability but newer phones and especially smart phones don't. And those older phones are usually not the most reliable devices to send and receive SMS messages from an external application. They are OK for small amounts of messages and when they are supervised, but often problematic in unsupervised systems.

If you have an Android phone lying around, you can try to use Diafaan SMS Server with our Android GSM Modem Emulator over a Wi-Fi connection. See our web page 'Use Diafaan SMS Server with Android phones' for more information.

Dedicated industrial GSM or 3G modems are usually the most reliable (depending on the mobile network). We have tested a couple of these modems here:
